Key Programmers

Modern cars typically require a key programming procedure to set up the car's system and allow the car to start. In certain instances the key needs to be programmed by an auto locksmith or dealer. The key may not work correctly or will not start the vehicle in any way. The reason for this is that the new key hasn't been programmed to the automobile's system - and this can be very costly. This is why it's a great idea to have two working keys for a modern car, so you can get the replacement key programmed when necessary.

Keyprogrammers are devices which can reprogram the transponder chip on a new key fob or mechanical key. It is also able to copy the data of an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with computers, and they also have a bidirectional interface for working with the immobilizer system.

There are a variety of keyprogrammers that are available on the market. They are available in a variety of shapes, sizes and colors.

Transponder Chips

Transponder chips can be found in cars that were manufactured within the past 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.

When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to determine if the transponder chip in the key is the correct one for your particular car.

This stops the vehicle from being started by either hot-wiring or by manipulating. The chip in the car key ensures that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip itself is housed within the plastic part of the key, and there are a few different types of cuts on these keys: a regular cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

A circuit inside the induction coil emits an electrical signal when the transponder is inserted into an ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer on the car recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the car isn't able to recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and an alarm. This is designed to deter people from trying to alter the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to bypass this system by employing a device designed to detect the signal.

As you can see there are quite a number of benefits to having transponder keys. All car owners should consider this when they want to safeguard their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking space, today's key fobs can also switch on the heated steering wheel or open all windows with a single push. These extra features could make it difficult to locate your car keys.

Key fobs make use of radio frequencies to communicate with one another and the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps keep others from stealing and re-transmitting the signal.

There are a few different ways to program a key fob depending on the model and make. You can sometimes do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.

When you hit the button on a key fob the microchip inside sends a code to the car's receiver it is paired with. The receiver compares this information with the signals that are allowed on the fob and either opens or closes the door. If the information doesn't match the fob's information, the car won't be allowed to operate.

Once the car is associated with a particular fob, it will only accept signals from the device. Other fobs won't work with the car, even though they appear like. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.

Most newer car dealerships will only work with cars with original fobs or genuine replacements sold by the manufacturer. It is because the only place with the experience to design a replacement fob is in the service department of the dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for dealers.
